Using a value returned from probe_read_str() to tell how many bytes to copy using perf_event_output() has issues in some older kernels, like 4.17.17-100.fc27.x86_64, so separate the bounds checking done on how many bytes to copy to a separate variable, so that the next patch has only what is being done to make the test pass on older BPF validators.

Add default handler for non-jump instructions. This really only has an effect on instructions that compute a PC-relative address, such as 'adrp,' as seen in these couple of examples: BEFORE: adrp x0, ffff20000aa11000 <kallsyms_token_index+0xce000> AFTER: adrp x0, kallsyms_token_index+0xce000 BEFORE: adrp x23, ffff20000ae94000 <__per_cpu_load> AFTER: adrp x23, __per_cpu_load The implementation is identical to that of s390, but with a slight adjustment for objdump whitespace propagation (arm64 objdump puts spaces after commas, whereas s390's presumably doesn't). The mov__scnprintf() declaration is moved from s390's to arm64's instructions.c because arm64's gets included before s390's. Committer testing: Ran 'perf annotate --stdio2 > /tmp/{before,after}' no diff. Signed-off-by:Kim Phillips <kim.phillips@arm.com> Tested-by:
